IIVEROVEMENT IN PAPER-FILES OR BINDERS.

' The Schedule referred to in these Letters Patent and making parl: of the same.

. -Hor To all whom it may concern Be it known that I, BERNARD J. BECK, of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Music-Binders, with buckle and needle; and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference beinghad to the accompanying drawing, and the letters of reference marked thereon, making part of this "specification, in

which- Figure 1 is an' end view.

Figure 2 is a plan view.

Figure 3 is a 4sectional view, at ythe point through which the cords pass through the sheets.

Figure 4 is 'plan and sectional views of the. clamping-buckle.

In the temporary binders for music, letters, 85e., heretofore used, it has been dihicult. to obtain suiicieut tension upon the binding-'cords or strings to cause the sheets to remain firmly together' at the back; hence, in opening and closing the sheets of paper in the iile, there has been more o`r less motion of the sheets on the strings or cords, rendering the holes large, and frequently causing the paper to tear; and it is well known' that the strength of the paper alone, at the part-s where the strings pass, is relied upon for holding the sheets in place.

"Ihe object of my present invention is to hold the sheets together much more firmly than heretofore, so 'as to relieve the strain upon the paper nearthe string, by the friction of the surfaces ot' the sheets of papel', for which purpose I employ a peculiar clamping-buckle and strings or cords.'

To enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

A A are the covers of pasteboard 4or, other suitable material, and

, a is the flexible back.

To one ofthe covers A, as shown at c, by any suitable means, I attach one end'ot' a cord, C.

At or near the saine, I secure a loop, d, to which is permanently fastened clamping-buckle, D. i

To the free end ot' the cord C, I attach a needle, E. This needle is composed ot' a flat metal-plate, and

provided with sharp cutting-edges e e at one end, and.'

with a double eye, c e', at the other.

This needle is much better suited for the purpose intended than the one with the ordinary bodkin-point "he sharp edges readily enable 'one vto make the c necessary perforations through any given number of sheets, and the double eye affords a secure means of fastening .the cord.

Thus I am enabled to use a single cord, and, at the ySametimes not subjected to the inconvenience of being compelled to draw a knot through each sheet, as

is the case with the needle having a single eye,.as you are forced, in order to secure the string, to tie the Y same.

The' clamping-buckle D is'formed with sides or flanges, 1,

journals 4 4,v and has an opening through its centre, for the cord or string to pass.,

In one end of the buckle D there is an opening, 5, by means of which it is secured to the loop d.

The other end is serrated at 6, iig. 4.

F I4" are eyelets in the covers A, through which the cord passes, and

G G are .recesses in the ends of the cover, which assist in retaining the cord in proper position.

The operationis as follows:

' One end of the cord C, and the loopd, that retains 'the buckle D, are permanently secured, as shown at c,

The needle E and cordfare thence passed through the eyelet F, perforat-ing the sheets, as'shwn atj and out through the eyelet F', and around the end of the boards resting in the recesses G G.

The needle and cord are then passed through the I opening in the metal clamp b. Y

The clamp is then forced down, as shown in plan view in lig. 4, and the cord securely retained between its outer face and the serrated end 6 of the buckle D. By this peculiar construction, the strings rcan be strained and held at any desired point, with whatever power the parts are capable of sustaining, so that the back edges of the cover will be firmly pressed upon the leaves or sheets, and while simply, by lifting the' clamp of the buckle, the cord or string can be immediately released and drawn out, should the same be desired.

Having thus fully described my invention,

What I-.claim therein as new, and desire to secure by Letters Patent of the United States, is-

'lhe string or cord C, when the saine is provided with a needle,'ld, having a double cutting-edge, c e, and eye, c e', and is fastened b`ya clamping-buckle, D, each feature being constructed and secured as shown, and the whole being combined and arranged so as to operate substantially as described, as and for the purpose specified.

In testimony whereof, I have signedmy name to this specification, in the presence of two subscribing 2, an'd 3 3, the sides or anges 3 3 forming y bearings for the metal clamp b, that swings upon thev
